G1010 Oxygen Analyser
Model: Mark II
Maker: Hitech Instrument
O/P type: 4 to 20 ma
O/P range: Programmable
The G1010 oxygen analysers have numerous applications in processes requiring the precise measurement of oxygen level. In ppm or % levels, safe areas or hazardous ones, in various process conditions and in differing backgrounds there is a G1010 configuration right for your needs. Options include a choice of outputs, AC or DC versions, alternative oxygen cells or sample conditioning.
Oxygen is measured in a wide variety of processes, to confirm its presence or absence. The most common application however is measuring oxygen as an 'impurity' in other gases, e.g. nitrogen generators. Oxygen is required in aerobic processes and also in situations that require user intervention, e.g. to ensure that it is safe to enter a chamber for maintenance work. Some processes will only run efficiently in the absence of oxygen, e.g. furnace atmospheres; others just require a low level of oxygen for safety reasons, e.g. inert gas blanketing.
Different electrochemical cells are available to suit the application. The standard ‘N’ cell has a broad range from high ppm to 50% oxygen. The ‘L’ cell is designed for accuracy at low ppm levels, it will also work at % levels (with a shorter lifetime). The ‘E’ cell is designed for use in % levels of oxygen in the presence of mildly acidic gases, e.g. carbon dioxide, while the ‘H’ cell is perfect for low ppm oxygen applications where hydrogen is present. Hitech will be pleased to advise on which cell is most suitable for an application.
A choice of configuration is available. The most convenient and economic is a standard analyser with the cell mounted on the rear. Alternatively, there is a remote sensor housing complete with flowmeter and valve. Where cable lengths and/or hazardous area conditions are an issue, the transmitter can be located in the sensor housing.
Different sample conditioning systems
are available, standard or bespoke, according to the process conditions. Filters, pumps and regulators can all be incorporated to deliver the sample in the correct condition. Bypass flow systems enable longer distances from process to analyser to be achieved. Hitech engineers are ready to recommend the right system for you on receipt of the full gas stream specification.
For hazardous area applications the sensor may be mounted remotely in the hazardous area and safely connected via an MTL zener barrier to the electronics unit in the safe area. Alternatively the electronics unit can be supplied in an EExd enclosure.
